* The Moon is a rocky body: It doesn't have an internal source of light like the Sun, which produces light through nuclear fusion.
* Sunlight illuminates the Moon: The Sun's rays hit the Moon's surface and bounce off, reflecting the light back towards us.
* The Moon's surface is rough: The craters, mountains, and dust on the Moon's surface scatter the sunlight, making it appear diffuse.
That's why we see the Moon as a bright, luminous object in the night sky!
